Doing some wiring and need to figure out what pin 114 (pink) is for. All I know is that it activates a relay and should be 11.0-14.0v, but I need to determine what relay it activates. The ADM version of the S15 FSM does not use this pin.

Also trying to figure out it says for pin 45 (BR/W). Also not part of the ADM FSM. I know it has something to do with the FICD solenoid, goes through a diode, and to a AC switch. I'm assuming the voltage is also to be 11.0-14.0v. So far, I've been told it would be a signal to bump up the idle when the AC is turned on (thank you Ted 510 owner).

See attachment for pictures.

Thanks for the translation.

114 says "Canister Purge Control Valve"

For pin 45 its:
A/Cリレー=AC Relay
FICDソレノイド=FICD Solenoid
A/Cコンプレッサー=AC Compressor
A/Cオートアンプ= AC Autoamp
外気温SW=Outside Temperature SW(switch?)

thanks Nisco!! I was about to type it all out, but I got pulled away from my computer

no problem:D

Curious to know what you're trying to do. Is this related to your ECU not seeing the AC signal in, so its not bumping the idle with the AC on?

Awesome. Thanks for the translations.

As far as what I'm trying to do, I'm just trying to complete all the circuits on the ECM harness. Some of the pins don't match the ADM S15 FSM, which is why I asked to translate the JDM FSM wiring schematic. I have yet to start the engine and check to make sure all the circuits are functioning correctly.

Since I don't have the AC system in the vehicle, this circuit will remain ignored. There is a separate pin (33 - Electrical load signal) which bumps up the idle when the headlights or defogger are in use. Took care of that one.

Shit, my issue is that my ECU isnt seeing the signal that the A/C is on. So the ECU isnt bumping the idle with the FICD. I dont even know where to start.

Well. If you did an engine swap like I'm doing, chances are you never completed that circuit. I have to start from scratch since I have a S15 engine in a S13 chassis. Since this circuit takes in 11.0-14.0V when the AC is on, you should be able to simply splice in a direct wire from the AC on/off switch wire right behind the climate control and take it directly to that pin. If the AC switch is not within that volt range (could be a 5.0v circuit), have it bump the idle when any climate control function is used (splice into the fan on/off signal wire). Or, you could set up a manual switch (make sure to fuse it w/ 10A) directly from the battery or preferably from the ignition wire. But again, that's assuming you don't have the circuit to begin with. If you have an actual JDM vehicle, then I couldn't explain it any better than the FSM. It's pretty right on and straight forward on how to figure out where the circuit is short or open.

Thats my issue, somebody said it could be a 5v circuit, I have no clue where to get a 5v source. I looked around the FSM and I couldnt find something that says its 5v. I dont wanna just jump it with a 12v and end up frying my PFC.

That's not a problem. I recently learned about a diode called a Zener Diode (you should notice the ECM and harnesses use diodes all over the place). This diode makes current flow one direction and limits the voltage down to a specific voltage (anywhere between 4-500v). So, in case it is a 5.0v input signal. Simply use some basic physics equations to determine the right amount of resistance you'll need, get the right resistor, pair it up with a Zener Diode, and you're set. Wire them up in series.

I have yet to try this out myself, but have a feeling I'll be doing this soon. Pin 37 on our ECM is a 5.0v input that is a power supply for our sensors, and I have yet to complete that circuit.
